Constructor & Destructor Documentation

ATSCStreamData::ATSCStreamData	(	int	desiredMajorChannel,
		int	desiredMinorChannel,
		bool	cacheTables = false
	)

Initializes ATSCStreamData.

This adds the PID of the PAT and ATSC PSIP tables to "_pids_listening"

Parameters:

	desiredMajorChannel	If you want rewritten PAT and PMTs for a desired channel set this to a value greater than zero.
	desiredMinorChannel	If you want rewritten PAT and PMTs for a desired channel set this to a value greater than zero.
	cacheTables	If true important tables will be cached.

bool ATSCStreamData::IsRedundant	(	uint	pid,

Returns true if table already seen.

Todo:

All RRT tables are ignored

Todo:

We don't check the start time of EIT and ETT tables in the version check, so many tables are improperly ignored.
